swIMP (SWIG-based Interfaces for Mathematical
Programming) aims to make solvers written in C or
C++ available under other languages. The current
focus is on Java as the target language and on
LP/IP-solvers which are compatible with the Open
Solver Interface (OSI) from the Coin-OR-project.
The wrappers are implemented using the generator
tool SWIG. swIMP has been started as a subproject
of Combean (also hosted at SourceForge).

swampex (or Swamp Explorer) is a cross-platform library designed to work with raster maps in Ozi Explorer format. Using this library, you'll be able to collect maps in the file system, get information about map calibration, find maps by latitude/longitude, render maps in SDL surfaces, and more.

sware is a Perl script to connect a SNOM 3x0
telephone to the databases of eGroupWare,
Open-Xchange, and vtiger to display addressbook
and calender entries on your SNOM telephone. It
uses LDAP or MySQL authentication. Incoming calls
are shown as a lastname or company name in the
display if the result is available in the
database.

swaret is an updater for Slackware and
Slackware-based distributions. It upgrades,
installs, re-installs, and downloads packages,
patches, sources (with build scripts), and much
more. Dependency support is included, which tracks
and fixes missing libraries for all packages.
Several Slackware Linux mirrors are used through
HTTP, FTP, rsync, or a local filesystem.
Third-party Slackware packages are availible on
LinuxPackages.net or other repository sites.
Internationalization (i18n) is supported.

swaret-tools is a set of scripts that can be used by a system administrator to set up a Slackware software repository and/or a mirror of the dependency file for swaret (an updating tool for Slackware).

SWISH stands for Simple Web Indexing System for
Humans. With it you can index directories of
files and search the generated indexes. Based on
EIT's swish, this is a cleaner-compiling, enhanced
version with better docs, better installation and
configuration tools, more sample configurations,
and a Web page to help manage index rebuilding.
SWISH is used with w4ais as a Web-based front end.

swordcoast.net IRCd is a fork of Undernet's IRCu
2.10.12 that features more possibilities for
network services, less power for IRC operators,
some of QuakeNet's Asuka patches, more versatile
host hiding, customizable whois information lines,
improvements for silence masks, and a few other
things.

swpartc is a simple but reliable utility for
copying the data contents of one file or
partition into another one and vice versa
without losing a bit. The partitions must have
the same size. It uses a crash recovery
technique (a small back-up file), which means
that even if the process is killed or the
computer crashes, the user can safely resume
the swapping operation later.

sxmppd is a server for the XMPP (Jabber) chat protocol. While other, functional XMPP servers exist, they are not as simple or have many dependencies. It supports user authentication, SSL, roster management,
presence updates and subscriptions, messaging (local users), group chat, and file-based server configuration.
